all you have to do is blitz Grossman and he's finished, he's too worried about getting hit and he tends to sidearm throws under pressure, goos quarterbacks understand that the blitz is a good thing if you get rid of the football quick, someone is always open down field.
He sidearms, throws off his backfoot, doesn't hold on to the football, takes sacks.......basically all the things you can't do as a quarterback in the NFL.
The bears offensive line is pretty good, but they won't block everyone all the time.
If teams like the Cards and Dolphins found ways to get to Grossman, the better teams will as well.
I actually like the Bears, but they need a QB who won't panic when the protection breaks down......
